Product Summary
The KS58006N is a DTMF/PULSE switchable dialer with a 32-digit redial which can be done using a slide switch. All necessary dual-tone frequencies are derived from a 3.579545 MHz TV crystal or ceramic resonator providing very high accuracy and stability. The required sinusoidal wave form for each individual tone is digitally synthesized on the chip. The generated wave form has very low total harmonic distortion (7% max). A voltage reference of the KS58006N is generated on the chip which is stable over the operating voltage and temperature range and regulates the single levels of the dual tone to meet telephone industry specifications. CMOS technology is applied to the KS58006N, for very low power requirements high noise immunity, and easy interface to a variety of telephones requiring external components.
